Abstract
A wire matrix print head has a first group of wires activated by a first group of electromagnetic means disposed on the circumference of a circle and substantially equally angularly spaced from each other. A second group of print wires is activated by a second group of electromagnetic means disposed on the circumference of a circle with each of the electromagnetic means of the second group having its longitudinal axis out of alignment with the longitudinal axis of each of the electromagnetic means of the first group. The print head includes guide means to transform the two groups of wires, which have their ends remote from the ends causing printing disposed on the circumferences of two circles, into a row and column matrix for causing printing.
